[PATCH iwl-next v5 11/12] ice: re-introduce ice_dealloc_flow_entry() helper

[Marcin Szycik <marcin.szycik@linux.intel.com>]

It was removed in commit ad667d626825 ("ice: remove null checks before
devm_kfree() calls"). Now it's useful again.

v5:
* ice_flow_acl_add_scen_entry_sync(), ice_flow_add_entry():
  ice_flow_acl_free_act_cntr() additions make more sense in patch adding
  this code, move them to that patch. Now this patch is a pure refactor.
v3:
* ice_flow_acl_add_scen_entry_sync(), ice_flow_add_entry(): call
  ice_flow_acl_free_act_cntr() in unroll
v2:
* Add this patch
